Mechanisms of predictive and diagnostic causal induction

In predictive causal inference, people reason from causes to effects, whereas in diagnostic inference, they reason from effects to causes. Independently of the causal structure of the events, the temporal structure of the information provided to a reasoner may vary (e.g., multiple events followed by a single event vs. a single event followed by multiple events). The authors report 5 experiments in which causal structure and temporal information were varied independently. Inferences were influenced by temporal structure but not by causal structure. The results are relevant to the evaluation of 2 current accounts of causal induction, the Rescorla-Wagner (R. A. Rescorla & A. R. Wagner, 1972) and causal model theories (M. R. Waldmann & K. J. Holyoak, 1992).     

Adolescent Perceptions of Parental Behaviors,Adolescent Self-Esteem,and Adolescent Depressed Mood

Using symbolic interaction, we developed a research model that proposed adolescent perceptions of parental support and psychological control would be related to adolescent depressed mood directly and indirectly through self-esteem. We tested the model using self-report questionnaire data from 161 adolescents living with both of their biological parents. To examine possible gender of adolescent differences, we tested two multigroup models separately for adolescents’ perceptions of mothers’ and fathers’ parental behaviors. Both the fathers’ and mothers’ models yielded (a) direct paths from self-esteem to depressed mood (for boys and girls), psychological control to depressed mood (for boys) and (b) an indirect path from support to self-esteem to depressed mood (for girls and boys) and an indirect path from psychological control to self-esteem to depressed mood (for girls). In addition, in the fathers’ model a significant direct path was found between fathers’ support and depressed mood (for girls).     

Rules-plus-exception tasks: A problem for exemplar models?

Erickson and Kruschke (2002b) have shown that human subjects generalize category knowledge in a rule-like fashion when exposed to a rule-plus-exception categorization task. This result has remained a challenge to exemplar models of category learning. We show that these models can account for such performance, if they are augmented with exemplar-specific specificity or exemplar-specific attention. This result, however, is only achieved if the choice rule that converts evidence for competing categories into probabilities is sensitive to small differences between evidence values close to 0. Exemplar-specific attention provided the best overall approximation of the data. Exemplar-specific specificity provided a slightly worse approximation, but it predicted better the rule-like generalization pattern observed.     

Does the type of judgement required modulate cue competition?

According to the comparator process hypothesis (Matute, Arcediano, & Miller, 1996), cue competition in the learning of between-events relationships arises if the judgement required involves a comparison between the probability of the outcome given the target cue and the probability of the outcome given the competing cue. Alternatively, other associative accounts (the Rescorla-Wagner model: Rescorla &Wagner, 1972) conceive cue competition as a learning deficit affecting the target cue-outcome association. Consequently, the comparator process hypothesis predicts that cue competition occurs in inference judgements but not in contiguity ones, for only the first type of judgement implicitly involves such a comparison. On the other hand, the Rescorla-Wagner model predicts cue competition in both inference and contiguity judgements, because it establishes no relevant role for the type of judgement in producing cue competition. In Experiments 1 and 2 we manipulated the relative validity of cues and the type of question (inference vs. contiguity) in a predictive learning task. In both experiments we found a cue competition effect, but no interaction between the relative validity of cues and the type of question, suggesting that the Rescorla-Wagner theory suffices to explain cue competition.     

Intrinsic Religiousness as a Mediator Between Fatalism and Cancer-Specific Fear: Clarifying the Role of Fear in Prostate Cancer Screening

Understanding factors that influence screening receptivity may enhance African-American men’s receptivity to prostate cancer screening. Men of African descent (N = 481) between the ages of 40 and 70 were recruited. The hypotheses that Fatalism would be related to Intrinsic Religiousness and Fear, Intrinsic Religiousness would act as a mediator between Fatalism and Fear, and Fatalism as well as Prostate Cancer-Specific Fear would be negatively related to past Prostate-Specific Antigen Testing and Screening Intent were supported. This meditational finding suggests that when religious beliefs are a motivating force, the fear-inducing effects of fatalism are reduced.     

Zhuangzi on Friendship and Death

Zhuangzi suggests that death is a transformation that we commonly and mistakenly think means the end of someone but really just marks a new phase of existence. This metaphysical thesis is presented at several points in the text as an explanation of distinctively Daoist responses to death and loss. Some (such as Wong 2006) take a Daoist response to death, as presented by Zhuangzi, to indicate dual perspectives on friendship and death. But I argue that the metaphysical view sketched above is consistent with a unified perspective, allowing the Daoist to enjoy deep friendships without risking some potential for grief typically associated with strong attachment. However, it leaves the Daoist best suited to friendships with those who endorse the same metaphysics. Furthermore, while the grief associated with the death of a friend is somewhat mitigated, the Daoist has reason to mourn even given this thesis.     

Why Bad People Can't be Good Friends

Must the best friends necessarily be good people? On the one hand, as Aristotle puts it, ‘people think that the same people are good and also friends’. But on the other hand, friendship sometimes seems to require that one behave badly. For example, a normally honest person might lie to corroborate a friend's story. What I will call closeness, which I take to include sensitivity to friends' subjective values and concerns as well as an inclination to take their subjective interests as reasons for action, is characteristic of friendship. But this seems to require that good friends should be morally flexible, more so than is compatible with a virtuous character. This would imply tension between ideals of friendship and ideals of character. But there is an important connection between virtue and friendship which arises precisely from friends' closeness, when concern for wellbeing, another important feature of friendship, is also taken into account. This helps mitigate the tension and shows how friendship and virtue are interconnected. The connection in turn provides friendship‐based reason to think the best friends must be good people, even though concerns of friendship may occasionally clash with other moral concerns.     

“Women Don't Get AIDS,They Just Die From It”: Memory,Classification, and the Campaign to Change the Definition of AIDS

In this paper, I examine activist group ACT UP's campaign to change the US Centers for Disease Control surveillance case definition of HIV and AIDS. This campaign's effects included a profound shift in how AIDS is understood, and thus in some real way in what it is. I argue that classification should be understood as a political formation with material effects, attending to the words of activists, most of them women, who contested the way AIDS was defined in a moment when no one else thought that definition needed to be changed. I argue that philosopher Sue Campbell's work on the importance of understanding memory and feeling as relational helps understand the histories of death and loss, resistance and fierce joy, crystallized in activist responses to HIV and AIDS.     

Facilitation and interference in the color-naming task

Two experiments were conducted to evaluate the phonological activation of the name of pictures when participants had to name the color in which these pictures were depicted. In Experiment 1, participants named the color of pictures whose names and color names shared the phonological beginning (phonologically related condition), the color of pictures whose names and color names did not share phonology (phonologically unrelated condition), and the color of abstract forms (neutral condition). A facilitatory effect was obtained, so participants were faster in the related condition than in the unrelated condition. However, naming latencies were similar in the neutral condition and the unrelated condition. In Experiment 2, the unrelated condition was replaced by a phonologically incongruent condition in which the name of the picture was phonologically unrelated to its color name but related to the name of other response color names. The results showed again a facilitatory effect when the related condition was compared with the incongruent condition. Importantly, an interference effect was also observed, so naming latencies were longer in the incongruent condition than in the neutral condition. These results are discussed in terms of language production models.
